IMPRvEME-NT IN wHlFFLETREEs.

Specification forming part of Letters Patent No. 145,826 dated December 23, 1873; application tiled August 19, 1873.

To all whom t may concern:

Beit known that I, HENRY AGAR, of Batavia, in the county of Genesee and State of New York, have invented an Improved Cross-Bar for the Thills or Pole of a Carriage, with springtrace coupling attached thereto, of which the following is a specification:

My invention relates to attaching a springtrace or tug-fastening to the cross-bar of the thills or pole of a carriage, so as to dispense with whifletrees, and increase the safety, economy, and lightness of the carriage.

In the accompanying drawings, Figure l is a plan View, showing the thills of a wagon with my spring-trace or tug attachment. Fig. 2 is a sectional View of same on the line x w, Fig. l.

A A represent the thlls; B, the cross-bar which connects them. G C are hooks, to which the traces are attached; they pass through holes or openings b, in the cross-bar B, close to the thills, and their rear ends are secured, by nuts c, to the free ends of short steel springs D D, the inner ends of which are securely bolted to the rear side of the cross-bar B. The springholds the hook closely to the bar when there is no draftrupon it, and when the tug or trace draws upon'v the hook it is held there by the tension, but the moment that is withdrawn the spring will bring the hook instantly' back to the cross-bar and prevent its being unhooked.

This arrangement dispenses with the use of whiffletrees, and can be used either with thills or the pole of a carriage. Itis much stronger, as the attachment is near the end of the crossbar, whereas Whifletrees are fastened near the middle, and the spring cannot break because it .bears upon the cross-bar when in use.A

I am aware of the Letters Patent granted to George and William Gibbs, March 10,1868, which show a double-tree the ends of which are encircled by clevises attached to springs, the latter being secured to the rear of the double-tree, and, therefore, I do not claim such as my invention.

What I (l tim as my invention is The hooks C, passed through the bar B and secured to the springs D, so that their hooked ends will be held against the bar B and prevent the disengagement of the traces when the draft is slackened, as set forth.

HENRY AGAR.
